MSI Z87-G43 PCI Express 3.0 Issues

SinSTAR360 · 31 Oct 2013 at 10:38

Been having a few issues with a new PC build - I'm a bit stumped now so wanted to see if anyone else has any ideas...

I have a MSI Z87-G43 Mobo and a HIS 7870 IceQ X 2GB GPU.

The system doesn't POST with the HIS card in the PCI-E 3.0 slot. (It works fine when plugged into another PCI-E slot on the board.)

HOWEVER...

I tried my brothers Sapphire 7870 GHz Edition in the same slot and the system runs perfectly.
I also checked the HIS card in another system's PCI-E 3.0 slot and that also worked fine!

So not really sure what the issue could be now, any advice appreciated

LOL I wish I could - the PSU power cables aren't quite long enough to reach the sockets on my card in his system - I tested the HIS card on my friends system

looked for bios updates for the his card? pretty sure there is one

also be sure to use latest motherboard bios,seen similar issue's with that card (his) and gigabyte boards

Thanks for the advice.

I believe I'm on the latest BIOs update for the board (1.50) and on first glance couldn't see a GPU BIOs update on the HIS website but will have another look!

your only losing 1% performance anyway but it should still work in the top slot

pretty sure its a bios bug somewhere that needs fixing

You can get extension cables for that, if you don't solve the problem and he is willing ofc
